PATENT OFFICE.

The present invention has a tool for attaching the fasteners to gloves or. other items of clothing. Such fasteners for clothing consist mostly of two parts, one of which is a securing part of the shape of a bowl, and the other an inner part Part with a flange; the flanged part enters the first and takes the fabric of the garment with it, which is to lie between the two parts comes, in which arrangement the edge or the edge of the fastening part the flange of the inner part is bent.

According to the invention, a die comes with a receding one. Surface for use; the same is for receiving and holding the cup-like fastening part determined and is best arranged in a yielding manner. Around this die is a helical shape coiled wire wound around it, which extends upwards over the support of the fastening part continues to hold it in place when the flexible material is slipped over. The lower end of the helically wound wire rests against a ring around the die; between Another helical spring is inserted into the die and a fixed foot, which yields under unusually strong pressure. A second die is located above the first die a tubular stamp. This second die is at its lower end with a conical surface, which is arranged around the punch; the latter is intended to hold the inner half of the clasp and is subject to the action of a Coil spring. The main purpose of the stamp is to serve the inner half of the closure with the fabric facing downwards into the bowl-shaped part. After The punch yields downward movement. The two parts are then united by the two actual dies and the conical ring-shaped surface surrounding the punch, the punch being the edge of the fastening part inwards and the fabric over the edge of the flange of the inner one Partly bends around. The second die can, if desired, be used for particularly strong pressure also be arranged resiliently, similar to the lower die. This indulgence has the purpose of removing the free edge of the fastening part without damaging the flexible one To bend the fabric over and inwards.

Fig. Ι shows in longitudinal section the upper and the lower die; between both dies are the parts of one half of the shutter. These parts are before the by one further movement of the dies takes place by bending the edge of the fastening part shown over the edge of the inner part.

Fig. 2 shows in vertical section the lower die alone and in a slightly modified form Execution. Fig. 3 shows a vertical section of the dies which make up the fastening part and hold the inner part of the cap sleeve before the union of these parts. Fig. 4 finally shows in section the upper die and the punch alone; the latter is split to hold a massive knob in place

Claims (6)

to be able to. The dies according to Fig. 3 and 4 are not shown compliant. Die α is recessed on its upper surface and receives the metal cup-shaped fastening part 2 of the closure. The die a has a diameter approximately equal to that of the fastening part 2 and is surrounded by an annular flange 3, protrudes into a fixed foot d and is flexible, in that a helical spring c is inserted between the feet d and the flange 3. . According to Fig. 1, the coil spring may c between the surface of the fixed Fufses and the lower surface of Flantsches 3 are, but may also shows, as Fig. 2, the fixed feet c a cavity for receiving the coil spring, and have the Flantsches 3. A resilient sleeve is pushed onto the die α , the upper part of which extends a little over the recessed surface of the die and which receives and surrounds the fastening part 2 when it is placed on the die and which holds it in place when the flexible fabric is placed over it; According to Figure 1, this flexible sleeve consists of a helical wire b which rests on the flange 3; it can also take the form of a metal ring e surrounding the upper part of the die (Fig. 2). This ring e then rests on a helical wire, which receives its support on the annular flange 3. The upper die f is tubular and receives the resilient punch g , which is likewise tubular at its lower end and is provided with a head at the top which rests against a surface in the die. In the axis of the die, on the head of the punch, lies a helical spring 4, which abuts against a screw plug 5 at the top; the latter can be readjusted to tighten the spring 4. The tubular lower end of the punch is, as shown in Fig. 4 can be seen split to receive the inner half of the clasp carrying a full button; in the arrangement of Fig. 1 this button is split while the tubular end of the punch is not split. The lower end of the die f is provided with an inwardly extending conical surface h which acts on the free edge of the fastening part 2 and bends it together with the flexible material 10 over the inner part 9 to close the parts of the closure half together associate. The position of the parts before the lowering of the die is shown in Fig. 1, after the lowering Fig. 5. If desired, the die f can be equipped with a fixed head i in which the said die can slide up and down. In this case, the die f is given a collar 6. A helical spring 7 is inserted between the latter and the lower surface of the head i. If the parts are arranged in this way the head / recess 11 must be provided through which a screw 12 is inserted from the outside in order to limit the up and down movement of the die f. The compliance of both joints is not absolutely necessary; usually a flexible one is sufficient Die off. The stamp g (Fig. 3) is tubular at its end and resilient fingers 8 are inserted into this end, the solid connecting piece of which is inserted into the solid part of the stamp g. The upper end of the ram can also be of tubular design to accommodate a helical spring 4. The punch in Fig. 3 receives the inner cap sleeve part k of the closure, the fingers 8 entering the opening of this inner cap sleeve part and "holding it by friction on the die f . The fabric 10 goes down over the edge of the outer, bowl-shaped part as well as under the flange of the inner cap sleeve or the inner button part and lies between the two parts. If the dies are brought closer together than indicated in Figs. 1 and 3, the conical surface h of the dies places the edge of the shell on the flange of the inner part, so that both parts hold tightly together. The action of the dies in connecting the parts of the cap sleeve and the button part is the same. Under the action of these dies, when they go downwards with the inner parts of the locking halves, sufficient force is accumulated in the punches to press the inner parts and the material down into the fastening part, whereupon the punch yields as the die moves further downwards the conical surface h of the latter folds the edge of the fastening part over the flange of the inner part. After the parts have been joined, the finished closure is removed from the upper die. Patent claims: ι. Tool for uniting the parts of a glove or other clothing fastener, consisting of a lower Die for receiving the one locking part and an upper die with inserted resilient punch, characterized in that the lower surface of the upper die is equipped with a conical cavity (h) surrounding the punch, for the purpose of placing the edge of the fastening part of one locking half on top of it To be able to lay down inner body.
A tool according to claim i, characterized in that the lower end of the punch (g) is tubular and split to accommodate a split button (Fig 4). Tool according to claim 1, characterized in that a flexible sleeve in the form of a helical spring (b) (Fig. 1) or a ring attachment (e) (Fig. 2) seated on a helical spring is arranged around the lower die (a) which protrudes a little over the upper end of the die to receive the fastening part and hold it on its seat. 1 sheet of drawings.
